Losing Power but Gaining Speed

Recently, an article was posted regarding the loss in power production of cyclists when they transition from a position on the hood to aerobars.  Among bike fit specialists and many high level cyclists, this is nothing new. It is common knowledge that the position of a time trial or triathlon bike is less bio-mechanically efficient than a road bicycle.  The goal with this position is not to increase a rider’s power output. It is to optimize the balance of efficiency and aerodynamics.

The key point here is that you, as an athlete, should be able to spend as much time in this position as possible.  If you are striving for a very “aggressive” aerodynamic position, it may take time for you to adapt. Unfortunately, we too often see people riding on the horns of their bars because they are uncomfortable in the aero position.  If you have been in the same position for more than 6 months on your TT/Triathlon bike, it is time to reassess your position.

Why is that the case?  Any time that you are out of the aerobars, you lose the vast majority of the purpose and function of your bike.  The other reason this is very important is because the recruitment of muscles is very different from the horns to the aerobars.  We are not only speaking of leg muscle recruitment (quadriceps, hamstrings, and glutes,) but also the utilization of neck, shoulder and back muscle recruitment that is varied by this position.
